Crab Stuffed Portabella Mushrooms

Crab Stuffed Portabella Mushrooms are the decadent appetizer that feels rich without being unhealthy.  I love using fresh portabellas in my recipes, but this makes them the star of the show.  Crab stuffed mushrooms with cheese are delectable on their own for any occasion, but serve it with some bubbly for a festive touch!

Crab Stuffed Portabella Mushrooms

This recipe stuffed mushrooms was created a few years ago one New Year’s Eve when we wanted something yummy and easy for an appetizer.  I left out the breadcrumb filler most recipes incorporate into stuffed mushrooms.

The succulent crab meat mixed with cheese and spices was more than enough to make these amazing. Topped with more cheese and a bit of butter, I couldn’t have asked for a better treat to celebrate a new year. 

For another delicious appetizer with that seafood appeal, my salmon patties are excellent and oh so easy to prepare.  We also love these smoked salmon deviled eggs and baked artichoke balls to add to an appetizer buffet. 

Here are the ingredients for crab stuffed portabella mushrooms all laid out before we begin!

Can I Use Button Mushroom Caps Instead?

I love portabella so I will often grab them or baby bella’s to use in my recipes, but a classic white button mushroom works just as well for this recipe.  You will just need to remove the stem and fill as you would the portabella. 

In fact, as long as the mushroom has a place for you to stuff the cra mixture, it will work just fine in this recipe.  I stick with bella and white mushrooms most often as they are the most versatile and readily available. 

The final touch for these stuffed mushroom with crab filling is to add the cheese on top!

Can I Use Imitation Crab for Stuffed Mushrooms with Crab?

In a pinch, you can use imitation crab.  It will give a different flavor and texture, and in my opinion not be as good. 

Honestly, I mostly use the crab that is in a can in the refrigerator section at the grocery store. It’s pricier than imitation crab for sure. If your budget allows, purchase fresh or canned crab.

If you want a crab dish without the crab, check out this crabless cakes in clouds idea using vegetarian crab cakes instead.  A great substitute without that allergic reaction potential imitation crab  would have on the menu. 

What is the Best Way to Clean Mushrooms?

Mushrooms absorb water so you don’t want to dunk them into a bowl of water or run them under the faucet to clean them. 

Instead, you want to use a dampened paper towel and individually brush all dirt off the outside of the mushroom. 

Yes, this adds a bit of time to the process, but it is also something you can assign to your kitchen helper (aka the kids) to do for you while you prepare the filling for the stuffed mushrooms. 

How to Make Stuffed Mushrooms Ahead of Time

These can easily go straight from the freezer to the oven which makes them a favorite!

To freeze them, I simply prepare up until the point of putting them into the oven.  Go ahead and line them up on your baking sheet, then put that baking sheet on a flat shelf of your freezer.  I lightly drape them with plastic wrap when doing this. 

Leave them in the freezer for around 1-2 hours to harden.  Then you can pick the mushrooms off the tray and drop them into a freezer bag or freezer storage container. 

When you are ready to bake them, just place them onto the backing sheet as directed and cook for an additional 5-10 minutes.  The time will depend upon the size of the mushroom and how hot your oven cooks. 

While your crab stuffed portabella mushrooms are baking, you can pop these bacon wrapped shrimp into the oven too for a piping hot delicious appetizer.

Tips for Serving Crab Stuffed Portabella Mushrooms

Once you pull these from the oven, you can decide if they are going to be setup on an appetizer tray, or if they are part of the main dish. 

I love displaying them on a platter with mini forks in them so they are easy to grab and eat.

Toothpicks are nice, but they are not sturdy enough to hold the weight of the mushrooms.  A miniature fork works great and also keeps your guests from having messy hands when eating these!

Delicious and decadent right out of the oven. Better than any other crab stuffed mushrooms I’ve eaten at restaurants. No joke!
